Acquisition [Abstract]

Acquisition

7. Acquisition

On April 1, 2011, the Company acquired all of the outstanding equity of Psytechnics, Ltd. (Psytechnics) a supplier of voice video network monitoring software. Psytechnics was acquired to expand NetScout's voice video monitoring capabilities using Psytechnics' existing software offering, Experience Manager. The results of Psytechnics' operations have been included in the consolidated financial statements since that date. The total purchase price of $17 million consisted entirely of cash consideration. The goodwill recognized primarily relates to the value in combining Psytechnic's product with our customer base.

The following table summarizes the allocation of the purchase price (in thousands):

Allocation of the purchase consideration:
Current assets, including cash and cash equivalents of $69		1,099
Fixed assets		50
Identifiable intangible assets		4,350
Goodwill		13,179
Total assets acquired		18,678
Current liabilities		(1,198	)
Deferred revenue		(466	)
	$	17,014

The Company has analyzed the realizability of the deferred tax assets of Psytechnics and has concluded that it is appropriate to provide a valuation allowance against these balances, given the weight of the historical objective evidence. The net asset balance reserved is $3.1 million and primarily consists of net operating loss carry forwards and tax basis in intangibles previously amortized for financial reporting purposes attributable to the U.K. operations of the acquired entity. The Company will continue to evaluate additional positive and negative evidence relating to the realizability of these assets within the first year of the transaction; any resulting changes to the valuation allowance attributable to facts existing as of the acquisition date but unknown at the time of the assessment would be recorded against goodwill. Any new facts resulting in changes to the valuation allowance will be recorded as a component of earnings.

Goodwill was recognized for the excess purchase price over the fair value of the assets acquired. Goodwill from the Psytechnics acquisition will be included within the Company's one reporting unit and will be included in the Company's enterprise-level annual review for impairment. No goodwill associated with this transaction will be deductible for tax purposes.

The following table reflects the fair value of the acquired identifiable intangible assets and related estimates of useful lives (in thousands):

	Fair Value		Useful Life (Years)
Acquired software	$	1,200		5
Customer relationships		450		10
Core technology		2,700		10
	$	4,350

The weighted average useful life of identifiable intangible assets acquired from Psytechnics is 8.6 years. These assets are amortized using an accelerated amortization method.

The following table presents the pro forma results of the historical Consolidated Statements of Operations of the Company and Psytechnics for the three and six months ended September 30, 2011 and 2010, giving effect to the merger as if it occurred on April 1, 2011 and 2010 (in thousands, except per share data):

	Three Months  Ended September 30,				Six Months  Ended September 30,
	2011		2010		2011		2010
Pro forma revenue	$	72,624	$	69,892	$	135,920	$	137,487
Pro forma net income	$	7,051	$	7,410	$	9,450	$	13,699
Pro forma income per share:
Basic	$	0.17	$	0.18	$	0.22	$	0.33
Diluted	$	0.17	$	0.17	$	0.22	$	0.32
Pro forma shares outstanding
Basic		42,258		41,922		42,433		41,867
Diluted		42,720		42,778		43,061		42,626

The pro forma revenue, net income and income per share for the three and six months ended September 30, 2011, is the same as the results reported in the Consolidated Statement of Operations of the Company for the three and six months ended September 30, 2011. The pro forma results for the three and six months ended September 30, 2010 primarily includes adjustments for amortization of intangibles, interest income and interest expense. This pro forma information does not purport to indicate the results that would have actually been obtained had the acquisition been completed on the assumed date, or which may be realized in the future.

Since the date of acquisition we have recorded $650 thousand of revenue earned by Psytechnics within our consolidated financial statements.
